The number of baseballs used in a Major League Baseball (MLB) season can vary depending on a number of factors, such as the number of games played, the number of home runs hit, and the number of foul balls and other balls that are lost or damaged during gameplay.
However, it is estimated that approximately 900,000 baseballs are used during the course of an MLB season. This includes all of the baseballs used in regular season games, as well as any balls used during the playoffs and World Series.
Each team typically uses between 90 and 100 baseballs during a single game, and many of these balls are discarded or replaced throughout the course of the game. Some balls may be lost or damaged beyond repair, while others may be taken out of play due to scuffing, dirt, or other factors.
To ensure a steady supply of baseballs throughout the season, MLB teams typically order large quantities of balls from the league’s official supplier, Rawlings. These balls are subject to strict quality control measures to ensure that they meet the league’s standards for size, weight, and performance.
